# PredictLeads vs Exa for finding similar companies (lookalike APIs), benchmarked

Both PredictLeads and Exa return companies that resemble a seed account — PredictLeads via similar companies via shared tech / news / jobs co-signals, Exa via neural company search from a seed-anchored capability query. Here is how they compare on identical B2B seed companies, scored by the same three-model LLM judge panel.

\[01\] head-to-head

## PredictLeads vs Exa, scored on the same seeds

Same input, same judge, same seed companies — so the gaps below reflect relevance, not different test sets. [See the full methodology and matrix →](https://openbenchmarks.com/lookalikes) 

| Metric | PredictLeads | Exa | Winner |
| --- | --- | --- | --- |
| Precision@10 (top-of-list quality) | **89.8%** | **80.8%** | PredictLeads |
| Precision@100 (long-list quality, headline) | **—** | **48.6%** | — |
| Relevant companies returned | **931** | **2,331** | Exa |

\[02\] how each works

## How PredictLeads and Exa find lookalikes

PredictLeads surfaces lookalikes via similar companies via shared tech / news / jobs co-signals; Exa via neural company search from a seed-anchored capability query. Same seed, same top-K, same LLM judge — so the mechanism difference shows up directly in the relevance numbers above.

\[03\] agent sign-up + use

## Agent sign-up and use instructions

How an agent runs a lookalike / company search on each — the access model (does the agent get in on its own, or does a human?), the exact call, and the credits.
